Wireless sound transmission and method
First Claim
1. A system for providing audio signals, comprising:
- an audio signal source to provide an audio signal;
a transmission unit comprising a digital transmitter for applying a digital modulation scheme to transmit the audio signal as audio data packets from the audio signal source via a wireless digital audio link,wherein the transmission unit is configured to encode the audio signal in such a manner that each audio data block is distributed onto at least two audio data packets in such a manner that one of the at least two audio data packets is a low-quality packet including an encoded low-quality portion of the audio signal, and one of the at least two audio data packets is a high quality packet that includes an encoded high-quality portion of the audio signal with regard to the low quality portion, so that by decoding of the low-quality audio packet only a low-quality portion of the audio signal is retrievable, whereas by decoding of both the low-quality and the high-quality audio data packets a high-quality portion of the audio signal is retrievable, andwherein the transmission unit is configured to transmit the low-quality audio data packet in a dedicated slot of a multiple access protocol frame and configured to transmit the high-quality audio data packet in another dedicated slot of the multiple access protocol frame; and
a receiver unit for reception of a modulated audio signal from the transmission unit via the wireless digital audio link,wherein the receiver unit is configured to receive and decode the low-quality audio data packet while sleeping during the slot dedicated to the transmission of the high-quality audio data packet.

Abstract
A system for providing sound to at least one user has at least one audio signal source, a transmission unit with a digital transmitter audio data packets from the audio signal source via a wireless digital audio link; at least one receiver unit having at least one digital receiver; and a hearing stimulator responsive to audio signals from the receiver unit. The transmission unit encodes the audio signal as audio data blocks distributed onto at least two audio data packets, one of which is a low-quality packet, and one of which is a high quality packet only a low-quality version of the audio signal being retrievable from the low-quality packets, and a high-quality version of the audio signal being retrievable from both the low-quality packets and the high-quality packets. The low-quality packets and the high-quality packets are transmitted in respective dedicated slots of a multiple access protocol frame.

20. A method for providing sound, the method comprising:
-
providing an audio signal from an audio signal source to a transmission unit comprising a digital transmitter for applying a digital modulation scheme; encoding the audio signal, wherein encoding includes encoding such that each audio data block is distributed onto at least two audio data packets in such a manner that one of the audio data packets is a low-quality audio data packet including an encoded low-quality portion of the audio signal, and one of the audio data packets is a high quality audio data packet including a high-quality portion of the audio signal with regard to a low-quality portion, so that by decoding of the low-quality audio data packet only the low-quality portion of the audio signal is retrieved, whereas by decoding of both the low-quality and the high-quality audio data packets a high-quality portion of the audio signal is retrieved; transmitting the encoded audio signal via a digital wireless audio link from the transmission unit to a receiver unit, wherein the low-quality audio data packet is transmitted in a dedicated slot of a multiple access protocol frame and the high-quality audio packet is transmitted in another dedicated slot of the multiple access protocol frame, and wherein the receiver unit is configured to decode the low-quality audio data packet only while sleeping during the another slot dedicated to the transmission of the high-quality audio data packet; decoding the transmitted audio signal; and providing the decoded audio signal to a user. - View Dependent Claims (21, 22)

23. A hearing device, the device comprising:
-
a housing structure configured to be worn by a human, a receiver unit physically coupled to the housing structure, wherein the receiver unit is configured to receive an audio signal from a transmission unit, wherein the transmission unit is configured to encode the audio signal in such a manner that each audio data block is distributed onto at least two audio data packets in such a manner that one of the packets is a low-quality audio data packet including an encoded low-quality portion of the audio signal, and one of the packets is a high-quality audio data packet that includes a surplus of an encoded high-quality portion of the audio signal with regard to the low quality portion, wherein the transmission unit is configured to transmit the low-quality audio data packet in dedicated slots of a multiple access protocol frame and to transmit the high-quality audio data packet in other dedicated slots of the multiple access protocol frame, and wherein the receiver unit is configured to decode the low-quality audio data packet while sleeping during the slots dedicated to the transmission of the high-quality audio data packet. - View Dependent Claims (24, 25)
